French Onion Chicken – Delicious, Easy, Cheesy & Low Carb!

French Onion Chicken

Easy, one dish, cheesy, delicious AND low carb?! This fantastic French Onion Chicken is what weeknight dinner dreams are made of. Chicken and caramelized onions cook together in a “French Onion” sauce and it is all topped with melted Swiss cheese. Throw everything in one oven safe skillet and “BOOM!” you have your family’s new favorite recipe in the rotation. We like to serve this up with a simple fresh side salad (and maybe a warm loaf of bread) and dig in!

Tips for making French Onion Chicken:

  • If you have one, use a cast iron skillet! Cast iron skillets are so versatile and they are perfect for this recipe because they can go from stove to oven with no issue.
  • If you don’t have beef stock on hand, beef broth will work as well. The flavor isn’t quite as concentrated in beef broth, but it will still be delicious.
  • Be sure to let your onions caramelize. This may be the most important part of this recipe. Caramalized onions have a very unique sweet flavor that would surely be missed!
  • Don’t skimp on the cheese! 8 slices may seem like a lot, but that distinct Swiss flavor is so delicious!

This recipe would go great with:

Simple Roasted Potatoes

Baked Havarti and Cheddar Mac and Cheese

Mashed Red Potatoes

Rosemary and Parmesan Focaccia

Or, just a fresh salad and some warm bread
